I don't see that this is much different than riding a nice round number of counts beyond where I should have stopped, freezing the front wheel, turning around, riding the same nice round number of counts in the opposite direction, then setting the point I should have set in the first place, then freezing the wheel, turning around, and continuing along my way.
Of course in doing so I don't have to worry about whether I stopped the wheel in the right part of the revolution so that it didn't record a spurious revolution or fraction thereof.
I appreciate the effort that has gone into developing alternative course measurement methods, but having tried at least one of them a number of times, I think the good old mechanical counter is hard to beat.
